What should happen when Chiba's hands grab on Liu's wrists? Who will manipulate whom? Also what if Brendan Lai grabs on Liu's wrist, Who will manipulate whom?

From Liu's point of view, the grabbing won't work. From both Chiba's and Brendan's point of view the grab work just fine. If one is right, the other one must be wrong. Do you see the "paradox" here?
